Application filed January 25, 1922. Serial .No. 531,785.

T all whom it may concern:

Be it known that Tnnooonn A. HAR- TUNG, a citizen of the United States,residing at Austin, in the county of Travis and State of Texas, haveinvented a new and useful Gravel Dump, of which the-following is aspecification.

v'llhis invention relates to wagon bodies, and more particularly to theconstruction of the bed or bottom thereof, i The primary object of theinvention is to provide a sectional-wagon bottom, novel means beingprovided for operating the sections to move the same to positions tocause material supported thereby, to; fall from the wagon body. I

Another object of the invention is to pro vide means for locking thesections of the wagon bottom against movement to insure the same beingheld in their closed positions.

A still further object of the invention is to provide means disposedadjacent to the operators seat for manipulating the operating means, tocontrol the movements of the sections of the bottom. v

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in thecombination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of'what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure l is a. fragmental elevational view of a vehicle, showing a bodyconstructed in accordance with the present invention, as appliedthereto.

Figure 2 is a plan view of the body.

Figure 3 is a bottom plan view of the body.

Figure 4 is a sectional view taken on line 4-40f Figure 2. a

Figure 5 is a transverse sectional view through the body of the device.

Figure 6 is a fragmental enlarged detail view disclosing the lockingmeans for. locking the sections of the bottom in their hori- Zontalpositions.

Referring to the drawings in detail, the body includes side members 5and end 1nembers 6 to which are secured side boards 7 and end boards 8.

F ormed in the end members 6 "and end boards 8, are slotted portions 9providing gu1deways for the locking plates 10 which move therein, theends of the guide plates 10 moving in suitable slots formed in the sidemembers 5 of the wagon body. [Rods 11 have their ends connected to theend members of the wagon body and are disposed in spaced relation,transversely thereof to provide supports for the sections 12, formingthe bottom of the wagon body.

Hinge members 13 are carried by the respective sections, and embraceportions of the rod 11 associated therewith to permit the sections 12 toswing downwardly and dis,-

charge material supporzted thereon. The rods 11 are also supportedintermediate their ends as by means of the hangers 14 which aresupported on the transversely extending rods 15 which have their securedto the side boards 7 in any suitable and well known manner, the hangers1 L being however of a thickness to lie between adjacent sections 1.2,These rods 15 brace the rods 11 at points inte rmediate-the endsthereof, the number of rods 15 being controlled by the length of thewagon body.

A rod 16 has its ends disposed within suitable openings formed in theside members 5, and are secured to the side boards 8 as by means of thebracket members 17. Mounted to rotate on the rod 16, are the controllingarms 18 which extend laterally therefrom and have openings 19 formed inthe free ends thereof, the openings 19 being designed to accommodatehook members formed at the upper ends of the connecting links 20, thelower ends of the connecting links 20 having suitable connection withadjacent sections 12 of the floor of the body, whereby movement of thelinks and controlling arms results in a relative movement of thesections.

Secured to the rods 16 and disposed at one end thereof, is an operatingarm 21, which is curved downwardly and formed with an eye to accommodateone end of the coiled spring 22, the opposite end of the coiled springbeing anchored to the wagon body as at 23. A suitable operating rod isindicated at 24 and has connection with the arm 21 at a point adjacentto the free end thereof, the opposite end of the operating rod 24 beingdisposed adjacent to the operators seat and provided with a suitablelever to control the movements of the rod to operate the arms 18.

Extending transversely of the wagon body, is a rod 25 which has its endsextended beyond the side boards of the body where the same support thelinks 26, the ends of the links 26 being formed with openings toaccommodate the inner ends of the rods 27 and 28 respectively, each ofwhich rods has connection with a pivoted bar 29, the lower ends of whichbars 29 being disposed in openings formed in the ends of the lockingplates 10, as clearly shown by'Figure 1 of the drawings.

In order that the, rods 27 and 28 may be operated to cause the operationof the locking plates, a controlling rod 30is provided, which also hasits forward end disposed at a point adjacent to the operators seat, andin easy access to the operator. It might be further stated that a plate31 is secured to the ends of each section 12, to reduce friction andwear between the sections 12 and vlocking plates 10, disposed at theends thereof.

From the foregoing, it will be obvious that a structure as disclosed isone wherein the operating arms and locking plates will be protectedagainst material such as sand or gravel from retarding movement of theoperating mechanism, to prevent the operation of the sections to dumpordischarge material supported thereon.

The operation is as follows:

Assuming that the wagon body is loaded with sand or gravel, and it isdesired to discharge the contents of the Wagon body. The rod 30 is movedto slide the locking plates to positions within the confines of theslotted portions 9. With the locking plates in this position, the rod24: is moved, causing the sections 12 to take positions with their sidefaces in parallel relation with each other, discharging the contents ofthe wagon body, between adjacent sections.

Having thus described the invention, what is claimed as new is In awagon body, side and end members, said end members having slottedportions formed in the inner surface thereof adjacent to their loweredges, locking plates adapted to slide within the slotted portions,means at each end of each locking plate for moving the locking plateswithin the slotted portions throughout their entire lengths of thelocking plates, a sectional bottom, the sections of the bottom beingpivotally supported, means for moving the sections of the bottom totheir active positions, and the ends of said sections adapted to rest onthe locking plates to hold the sections of the bottom in their activepositions.

In testimony that I claim the foregoing as my own, I have hereto aiiixedmysignature in the presence of two witnesses.
